Purpose Overactive neutrophils are thought to be key drivers in the development of post-traumatic multiple organ dysfunction syndrome (MODS). Little is known about the role of inflammation-related lnc-IL7R in trauma. Thus, we aimed to explore the association between neutrophil-derived lnc-IL7R and post-traumatic MODS. Methods Total RNA was extracted from the isolated circulating neutrophils in 60 patients with trauma and 33 healthy volunteers for lnc-IL7R expression determination by real-time PCR. The correlation of lnc-IL7R expression with disease severity and the development of post-traumatic MODS was analyzed. Results The lnc-IL7R levels were significantly lower in trauma patients, especially in those with severe trauma [Injury Severity Score (ISS) ? 16], and correlated negatively with the ISS, Acute Physiology and Chronic Health Evaluation II score, and length of ICU stay. The lnc-IL7R levels were also significantly decreased in patients who developed MODS than in those who did not. Lnc-IL7R was an independent predictor of MODS [odds ratio (OR) 0.654, (0.435-0.982), p = 0.041]. The area under the curve for predicting post-traumatic MODS was 0.799 (sensitivity 76.9%, specificity 71.4%), with a cutoff value of 0.024. Conclusions Neutrophil-derived lnc-IL7R is an independent predictor of post-traumatic MODS; therefore, it could be a useful predictive marker for MODS.Purpose Various population-based cohort studies have shown that antimicrobial agents increase the risk of overanticoagulation in patients using coumarins. In this study, we assessed this association in hospitalized patients. Methods We included all patients hospitalized in the Spaarne Gasthuis (Haarlem/Hoofddorp, the Netherlands), who started using an antimicrobial agent during acenocoumarol treatment or vice versa between 1 January 2015 and 1 July 2019. Patients were followed from start of concomitant therapy until 48 h after termination of the concomitant therapy or discharge, whichever came first. We analyzed the association between the antimicrobial agents and the risk of overanticoagulation, defined as an interpolated INR above 6, using Cox regression analysis. We corrected for multiple testing with the Bonferroni correction. Patients who started using acenocoumarol and amoxicillin/clavulanic acid were used as reference group. https://www.selleckchem.com/products/crt-0105446.html Results In the study population, sixteen antimicrobial agents were started frequently concomitantly with acenocoumarol treatment. We included 2157 interaction episodes in 1172 patients. Patients who started using the combination of co-trimoxazole (HR 3.76; 95% CI 1.47-9.62; p = 0.006), metronidazole (HR 2.55; 95% CI 1.37-4.76; p = 0.003), or itraconazole (HR 4.11; 95% CI 1.79-9.45; p = 0.001) concomitantly with acenocoumarol treatment had an increased risk of overanticoagulation compared with patients using acenocoumarol and amoxicillin/clavulanic acid concomitantly. The associations for metronidazole (p = 0.045) and itraconazole (p = 0.015) remained statistically significant after correction for multiple testing. Conclusion Co-trimoxazole, metronidazole, and itraconazole increase the risk of overanticoagulation in patients using acenocoumarol. These combinations should be avoided if possible or otherwise acenocoumarol doses should be reduced and INR measured more frequently.The dysregulation of Ras/Raf/MEK/ERK pathway governs occurrence and progression of cancers. In previous studies, genome-wide association studies (GWAS) have identified multiple gene loci related to gastric cancer. However, a great many genetic loci have been missed due to multiple statistical comparisons of GWAS. In this study, Multi-marker Analysis of GenoMic Annotation (MAGMA) was applied to analyze genes in Ras/Raf/MEK/ERK pathway and their single nucleotide polymorphisms (SNPs) based on Chinese GWAS including 1625 gastric cancer cases and 2100 controls. The SNP effects on gastric cancer susceptibility were calculated on the basis of a logistic regression model. Expression quantitative trait loci (eQTL) analysis was performed based on the genotype-tissue expression (GTEx) project. We identified that three SNPs in MAP2K1, rs4287513, rs76906202 and rs11631448 were markedly associated with gastric cancer risk (rs4287513 OR = 1.30, 95% CI = 1.10-1.54, P = 1.92 × 10-3; rs76906202 OR = 0.87, 95% CI = 0.79-0.96, P = 3.72 × 10-3; rs11631448 OR = 1.21, 95% CI = 1.05-1.39, P = 6.74 × 10-3). All the loci were eQTLs for MAP2K1 in normal gastric samples. Moreover, the low expression of MAP2K1 was significantly associated with poor survival in gastric cancer patients. Thus, MAP2K1 might represent a key gene related to gastric cancer in Ras/Raf/MEK/ERK pathway, whereas SNPs in MAP2K1 confer gastric cancer susceptibility by having biological effects on the MAP2K1 expression.The immune system plays a pivotal role in maintaining the defense mechanism against external agents and also internal danger signals. Metabolic programming of immune cells is required for functioning of different subsets of immune cells under different physiological conditions. The field of immunometabolism has gained ground because of its immense importance in coordination and balance of immune responses. Metabolism is very much related with production of energy and certain by-products. Reactive oxygen species (ROS) are generated as one of the by-products of various metabolic pathways. The amount, localization of ROS and redox status determine transcription of genes, and also influences the metabolism of immune cells. This review discusses ROS, metabolism of immune cells at different cellular conditions and sheds some light on how ROS might regulate immunometabolism.Purpose To evaluate the variability of quantitative measurements of metastatic liver lesions by using a multi-radiation-dose-level and multi-reader comparison. Methods Twenty-three study subjects (mean age, 60 years) with 39 liver lesions who underwent a single-energy dual-source contrast-enhanced staging CT between June 2015 and December 2015 were included. CT data were reconstructed with seven different radiation dose levels (ranging from 25 to 100%) on the basis of a single CT acquisition. Four radiologists independently performed manual tumor measurements and two radiologists performed semi-automated tumor measurements. Interobserver, intraobserver, and interdose sources of variability for longest diameter and volumetric measurements were estimated and compared using Wilcoxon rank-sum tests and intraclass correlation coefficients. Results Inter- and intraobserver variabilities for manual measurements of the longest diameter were higher compared to semi-automated measurements (p less then 0.001 for overall).
